From Logical ID

This field contains the logical ID of the system that is sending the Business Object Document (BOD).

In the Replication Document Inbox, the value in this field is taken from the inbound BOD and is the logical ID for the system from which the BOD was sent.

In the Replication Document Outbox, the value in this field is the logical ID for your location and Mongoose-based application.

In both cases, the value in this field should be the same as the value in the Logical ID field.
